Neurospora - an ascomycetes fungus has been used as a biological tool to understand the mechanism of plant genetics much in the same way as Drosophila has been used to study animal genetics. What makes Neurospora so important as a genetic tool?

Answer:
Due to following reasons Neurospora is used as a genetic tool :
• Fastest growing in vitro, can be grown in minimal media.
• Due to its haploid nature it can express both dominant as well as recessive traits.
• Analysis of genetic combination is facilitated by the ordered sequence of the products in the form of eight ascospores [result of meiosis and mitosis].
• Release of ascospores per ascus takes place systematically i.e. one by one, so that single ascospores in an orderly sequence can be isolated in successive single spore culture.
• All the seven chromosomes of Nuerospora are either telocentric and achrocentric.
Hence genes can be easily mapped......

Answer:
It is because of the following reasons :
It is because of the following reasons :(a) It is haploid so recessive traits can be studied.
It is because of the following reasons :(a) It is haploid so recessive traits can be studied.(b) A lot of information is available about its genome.
It is because of the following reasons :(a) It is haploid so recessive traits can be studied.(b) A lot of information is available about its genome. As a result of sexual reproduction, it produces 8 ascospres which show a specific arrangement. This helps to study recombination.
Hope this will help you ✌️
